eval_TGASP: T-GASP emulator

In LinkedGASP: Linked Emulator of a Coupled System of Simulators

Description

This function evaluates the third GASP of a computer model within objective Bayesian (OB) implementation of the GASP, resulting in T-GASP.

Usage

eval_TGASP(input, GASPparams)

Arguments

input	Input values (the same dimension as training input data in the next argument GASPparams)
GASPparams	The output of the function eval_GASP_RFP.

Value

Function returns a list of three objects

x	Inputs.
mu	Mean of an emulator.
var	Covariance matrix of an emulator.

Examples

## Function f2 is a simulator
f2<-function(x){cos(5*x)}

## One-dimensional inputs x2
x2 = seq(-0.95,0.95,length = 6)
data.f2 <- list(training = x2,fD = f2(x2), smooth = 2)

## Evaluation of GASP parameters
f2_MLEs = eval_GASP_RFP(data.f2,list(function(x){x^0},function(x){x^1}),1,FALSE)

## Evaluation of a T-GASP emulator
TGASP_f2 <- eval_TGASP(as.matrix(seq(-1,1,.01)),f2_MLEs)
